Booking a DJ for a 30th or 50th birthday party sets the whole mood, but good talent gets booked months in advance. If your event falls in off-peak months like March or October, you have a great window to lock in a date before venue schedules fill up.
A quality DJ usually costs around $1,500. Spreading that cost out over time gives you space to pay for catering, venues, and decor without draining your savings all at once.
Remember that an intro window is a strict deadline, not free money. If you still have a balance on the Citi Simplicity® Credit Card after the 18 months end, you will owe the standard regular interest rate on whatever balance remains.
